Abstract
Intravenous glucose tolerance tests were carried ont on forty patients with recent myocardial infarction and thirty-nine matched controls with recent bone injury. Abnormal results were detected in 77·5% of cardiac patients and 68% controls. When tests were repeated after acute stress factors had settled, normal results were obtained in 85% of thirty-three cardiac subjects and 84% of thirty-eight controls. It is concluded that the disturbance of glucose tolerance in myocardial infarction is a non-specific stress effect and should not be regarded as necessarily indicating a latent diabetic tendency.
